1. Statistical processing of Flash X-ray Imaging of protein complexes
Abstract : Flash X-ray Imaging (FXI) at X-ray Free Electron Lasers (XFELs) is a promising technique that permits the investigation of the 3D structure of molecules without the need for crystallization, by diffracting on single individual sample particles.In the past few years, some success has been achieved by using FXI on quite large biological complexes (40 nm-1 μm in diameter size).

2. Simulations of ultrafast photon-matter interactions for molecular imaging with X-ray lasers
Abstract : Biological structure determination has had new avenues of investigation opened due to the introduction of X-ray free-electron lasers (XFELs). These X-ray lasers provide an extreme amount of photons on ultrafast timescales used to probe matter, and in particular biomolecules. READ MORE

3. Simulations of Biomolecular Fragmentation and Diffraction with Ultrafast X-ray Lasers
Abstract : Studies of biomolecules have recently seen substantial developments. New X-ray lasers allow for high-resolution imaging of protein crystals too small for conventional X-ray crystallography. Even structures of single particles have been determined at lower resolutions with these new sources. READ MORE

4. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering
Abstract : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. READ MORE

5. Structural studies of ba3-type cytochrome c oxidase using serial crystallography and X-ray absorption spectroscopy
Abstract : Cytochrome c oxidase (CcO) catalyses the reduction of molecular oxygen to water while the energy released in this process is used transport protons “up-hill” across an energy transducing biological membrane, creating a proton-motive force for ATP synthesis. Given its key role in energy transduction in organisms, proton pumping has been extensively studied across species. READ MORE
